Understanding the Law
What Is First DUI Offense California Under California Law?
A first DUI offense in California under VC §23152 is charged as a misdemeanor in the vast majority of cases. First offense means no prior DUI convictions within the past 10 years — California looks back 10 years when determining prior DUI offenses for sentencing purposes.
Despite being a misdemeanor, a first DUI conviction has serious long-term consequences beyond the immediate penalties. It creates a 10-year lookback period during which any subsequent DUI will be treated as a second offense with significantly harsher penalties. It triggers mandatory DUI school, probation, and SR-22 insurance requirements. And it creates a permanent criminal record that cannot be expunged while you are on probation.
The good news: first-offense DUIs are the most defensible DUI cases. Borderline BAC results, calibration issues with the breathalyzer, improper stop, or weak field sobriety test performance can all create reasonable doubt. A wet reckless reduction is most available on first-offense cases. Prefile intervention — contacting the DA before formal charges are filed — is also most effective on first offenses.
Elements of the Crime

- 3The driving occurred within the relevant time period (BAC must be measured within 3 hours of driving for the per se theory)

Defense
Defense Strategies for First DUI Offense California Charges
Wet Reckless Negotiation
A reduction to wet reckless (VC §23103/23103.5) is the most common resolution for first-offense DUI cases with borderline facts. A wet reckless carries lower fines, shorter DUI school (typically 6 weeks vs 3 months), no mandatory IID, and less insurance impact than a DUI conviction. We pursue wet reckless reductions aggressively on all eligible first-offense cases.
Challenge the BAC Result
A BAC reading of 0.08% or 0.09% — especially on a breath test — is not an automatic conviction. Breathalyzer margin of error, rising BAC defense, mouth alcohol contamination, improper calibration, and failure to observe the required 15-minute pre-test waiting period can all undermine the per se theory under VC §23152(b).
Suppress Evidence from Illegal Stop
If the officer lacked reasonable suspicion to stop your vehicle, all evidence obtained after the stop is suppressible. We obtain dashcam footage, review the officer's report, and challenge the constitutional validity of the traffic stop in every case.
Prefile Intervention
The 30–60 day window between arrest and arraignment is the best time to resolve a first-offense DUI favorably. We contact the assigned deputy DA directly, present mitigating evidence (employment, family, community ties, lack of prior record, voluntary DUI school enrollment), and negotiate for reduced charges or case rejection before formal charges are filed.
Fight the DMV Hearing
The DMV APS hearing is a separate proceeding from the criminal case and must be requested within 10 days of arrest. Winning the DMV hearing preserves your driving privileges even if the criminal case proceeds. We subpoena the arresting officer, challenge the validity of the blood alcohol test, and argue for a set-aside of the suspension at every DMV hearing.

Questions
Frequently Asked Questions — First DUI Offense California in California
Will I go to jail for a first DUI in California?
Most first-time DUI defendants in Los Angeles County do not serve significant jail time. The statutory minimum is 96 hours but judges routinely grant probation with little to no jail for first offenders with no accident and no injury. Work release, house arrest, or informal probation without custody are common outcomes on first-offense DUI cases defended by an experienced attorney.
How long does a first DUI stay on my record in California?
A DUI conviction stays on your California DMV record for 10 years — this is the lookback period for determining prior DUI offenses. On your criminal record, a DUI conviction is permanent unless expunged under PC §1203.4. You are eligible to petition for expungement after completing probation. Once expunged, you can legally answer 'no' to most private employer background check questions about convictions.
Can I get a DUI expunged in California?
Yes. After successfully completing your DUI probation — typically 3–5 years — you can petition to have your first DUI conviction dismissed under PC §1203.4. An expungement does not erase the conviction from your DMV record, it does not restore your gun rights if you lost them, and it does not prevent the DUI from being used as a prior conviction in future DUI cases. But it does allow you to legally say you were not convicted on most employment background checks.
What is a wet reckless and is it better than a DUI?
A wet reckless is a plea to reckless driving involving alcohol under VC §23103/23103.5 — it is almost always a better outcome than a DUI conviction. A wet reckless typically carries lower fines, shorter DUI school, no mandatory IID requirement, and less impact on insurance premiums. However it still counts as a prior DUI offense if you are arrested for DUI again within 10 years, so it is not a complete victory — just a significantly better outcome.
Do I need a lawyer for a first DUI in California?
Yes. A first DUI conviction has consequences that follow you for 10 years — increased insurance, criminal record, professional license impacts, Watson advisement. An experienced DUI defense attorney can challenge the evidence, negotiate a reduction to wet reckless, win the DMV hearing, and in some cases get the case dismissed entirely. Public defenders handle hundreds of cases — private DUI defense gives you dedicated attention at the most critical stage of your case.
What is the 10-day rule after a DUI arrest in California?
After a DUI arrest in California, the officer typically confiscates your license and issues a pink temporary license valid for 30 days. You have exactly 10 calendar days from the date of arrest to contact the DMV and request an Administrative Per Se (APS) hearing. If you do not request the hearing within 10 days, your license is automatically suspended after 30 days regardless of what happens in the criminal case.
